Construction Details
The SCI S3716RC family is designed as a cast stainless steel reducing coupling with socket-weld connections at both ends.
The fitting uses 316 stainless steel castings conforming to ASTM A351 ACI Grade CF8M, providing corrosion-resistant construction for compatible stainless steel piping systems.
Unlike a full coupling, the reducing configuration connects two different nominal pipe sizes while maintaining a straight in-line piping arrangement.
Reducing Design & Typical Applications
Reducing Coupling Design
- Straight in-line transition
- Two socket-weld connections
- Different connection sizes
